United States Patent Ofiice 3,160,927 Patented Dec. 15, 1964 3,166,927WINDOW AFETY GUARD Nicholas F. Basilio, 134% Woodland Road, Rydall, Pa.Filed May 29, 1963, Ser. No. 284,193 1 flaim. (Ci. 2l---71) Thisinvention relates to a window safety guard and, in particular, to asafety guard which is designed to be inserted and removed from anordinary window frame as desired, while preventing access through theopen window when in the inserted position.

It is the primary object of this invention to provide a window safetyframe which can easily be inserted in an ordinary window frame whereinonly a few locking parts are permanently installed, the safety guardhaving locking means which can quickly be engaged and release It isanother object of this invention to provide a light weight window safetyguard of inexpensive construction having locking apparatus which is sodesigned that a child on the inside of the window could not unfasten andremove the frame by himself. I

These objects and other attendant advantages will become more apparentfrom the description herein and from the attached drawings, wherein:

FIG. 1 is a perspective View of an ordinary window having two sashesmounted for vertical movement, with one form of the safety guard of thisinvention shown in the installed condition;

FIG. 2 is a fragmentary perspective view of the window guard employing amodified locking apparatus;

FIG. 3 is a sectional view, partly in elevation, of the two sashesshowing the safety guard in position before locking;

FIG. 4 is a sectional view, partly in elevation, taken along the linesand arrows IV-IV of FIG. 1, showing the inner sash in the loweredposition;

FIG. 5 is a sectional view, partly in elevation, showing a modificationof the locking means with the inner sash raised;

FIG. 6 is a sectional view taken along the lines and arrows VIVI of FIG.2 showing the inner sash lowered;

FIG. 7 is a sectional view taken along the lines and arrows VIIVII ofFIG. 1 showing the two sashes locked together; I

FIG. 8 is a sectional view taken along the lines and arrows VIIIVIII ofFIG. 1;

FIG. 9 is a perspective view of a locking member; and

FIG. 10 is a perspective view of a locking member and a holding meansforming a modification of the holding means shown in FIG. 9.

Referring, preliminarily, to FIG. 1 of the drawings, an ordinary windowframe is generally designated by the numeral 10 and consists of twovertical side frame members 12 and 14, a top transverse member 16 and asill18 located at the bottom of the frame 10. Mounted within the windowframe 10 are two sashes, an inner sash 20 and an outer sash 22, shown inbroken lines. Both sashes, as is the ordinary practice, are mounted forvertical movement within the window frame 10. It should be understood,however, that the safety guard of this invention need be only slightlymodified so as to accommodate sashes which are mounted for horizontalmovement.

The preferred form of the window safety guard of this invention, shownin FIGS. 1 and 2, is generally designated by the numeral 36. This formconsists of a frame- 32 extending around the guard, the frarne 32 beingsubstantially the size of a single window sash so that it occupiescompletely the lower half .of the window. Within frame 32 arepermanently mounted a plurality of bars or cables 34 preferably of astrong metal, so that passage through the center of the frame isprevented. These bars can be of any desired shape and form and can beattached to the frame 32 as desired. Two U-shaped channels 36 arepermanently fixed to the vertical window frame members 12 and 14 at thebottom. These channels 36, each having :a single open end 36a, aremounted inside the inner sash 20 so that when the safety guard 30 is notin place within these channels as shown in FIG. 1, the channels 36 donot in any way hinder movement of either sash or full utilization of thewindow. The channels are preferably formed from a metal such as aluminumor iron and can be secured to the window frame by any suitable means.

The safety guard frame 32 itself is of such thickness and width as toslide easily in the channels 36 but be firmly held therein so that theguard is inserted in the channels by dropping it in the open ends 36a.

The window safety guard locking means 49, as shown in'FIG. 1, consistsof a round metal bar having oppos ingly directed end portions 40a, 40b,shown in greater detail in FIG. 9. When the safety guard is in place,the end portion 46b is mounted within a circular channel or hole in thetop edge of the guard frame while portion' 40a is similarly mounted inthe bottom edge of sash 20 as described hcreinbelow.

A modification of the lockingmeans is shown in FIG. 2 a

FIG. 3 is a sectional view of the two sashes and shows bar 40 mountedwithin a circular channel or hole 38 formed in the top of guard frame32. Both the inner sash 20 and the outer sash 22 are raised to the topof.

the window frame and above the safety guard so that bar 40 is positionedto slide within channel 21 in the bottom of the inner sash where thatsash is lowered. In FIG. 4,

the inner sash 20 has been lowered so that the upper por- 3 ton 49a ofthe bolt 44} fits within the circular channel 21 made in the bottom ofthe sash 20. When bar 40is'fitted within both the safety guard and theinner sash, the safety guard cannot be moved vertically'out of channel36 until the sash 20 is raised so as to clear the upper bar portion 40a.Bar 40 can'be pivotally mounted in'guard frame 32 so that the barremains in the plane of the safety guard while the guard is inserted inchannel 36 after which the bar is pivoted to the position shown in FIGS.3 and 4. I

Referring now to FIGS. 5 and 6 wherein a modification of the lockingmeans shown in FIGS. 3 and 4 is illustrated. The locking means of FIGS.5 and 6 correspond to that shown in FIG. 2 and comprises a locking bar50 having a lower portion 50b mounted within a circular channel 39 inthe top of the guard frame. portion 50a is located land remains in thesame plane as the window guard substantially as shown. A catch 54,secured by a pair of screws 56, is mounted on the lower inner edge ofthe inner sash- 20 in a position so as to receive the upper bar portion50a when the latch 20 is moved downwardly as shown in FIG. 6. After thesafety guard has been placed within channels 36 the inner sash islowered, as shown in FIG. 6, and the bar 50 slides within the raisedsection 54a of the catch 54.

Referring now to FIG. 7, a locking pin 60 having a catch chain 62 isprovided to prevent the inner sash'from being raised while the guard isin position. The pin 60 extends through a bore 28 in the topof the innersash The upper In FIG. 8, a bottom stud 70 is shown mounted within thebottom edge of the guard frame 32 and within a channel 72 in the windowsill'l 1 Stud 70 prevents movement of the window guardeither inward oroutward at the bottom edge and the stud70 fits into the circular channel'72'in the sillas the guard is lowered into position. 1

In FIGS. 9 and 10, the locking means consisting of bars 40 and 50, andcatch 54 are shown in greater detail. opposingly directed end portionsand are normally formed from a strong metal such as iron.

The operation of this form of the window safety guard of my invention issubstantially as follows. desired to have the window opened ,but haveprotection against someone coming in'or a child falling out of thewindow, the window guard of this invention is utilized.

It can be observed that the bars are formed having" When it is Thesafety guard is slid into thee-pen ends of the two U- 7 channels alreadyattached to the window frame until the serted so that catch- 54 willclearthe guard. The inner sash is then lowered until the locking barsfit'either within the groove in the bottom of the sash or in the catchas shown. Then the top locking pin is inserted through the innersash-until it engages the outer sash thereby preveutingmovement of theinner sash upwardly. With the inner sash locked against verticalmovement, the safety' guard cannot be removed from the window because itis held at the sides by the U-channels, at the top by the locking pinand at-the bottom by the stud. It should be clear that the locking pincannot be removed by some one on the outside because the two sasheshaving glass therein occupy that portion of the window. From the inside,.the locking .pinis positioned relatively high in the window so that asmall child would be unable to I grasp the pin and remove it. Even if achild did remove the pin,.it is doubtful that he could raise the" innersash and lift the safety guard entirely out of the channels,

The safety guard of my invention may be made in a variety of materialsbut it is preferred that the guard be relatively light in weightyet-consistent with the degree of strength required. A wooden framecould support the metal bars as shown in FIG. 1.

Although this invention has been described with reference to specificforms and embodiments thereof, it will be apparent to those skilled inthe art that various changes other than those referred to above may bemade in the form of the apparatus, that equivalent elements may besubstituted for those illustrated in the drawings, that parts may bereversed, and that certain features of the invention may be used toadvantage independently of the use of other features, or within thespirit and scope of the invention as defined in the appended claims.
